Assignment Problem:
In this experiment, the student will become familiar with basic circuit implementation in LTSpice and with using the lab equipment to be utilized throughout this course. In LTSpice there will be DC and AC circuit simulation, Transient and AC analysis exercises. In the lab, the equipment to be used includes the ADK oscilloscope, ADK signal generator and ADK network analyzer.
In this lab, the student is expected to learn the order lab data should be collected for report purposes, LTSpice and equipment setup and measurements, thus this experiment is structured and step by step instructions are provided to achieve those objectives, later labs will not include this format or level of detail except for special cases.
Post-lab Questions: (These are theoretical questions. Use LTSpice and calculator)
Question 1: With respect to AC parameters, what type of Voltage or Current measurement is taken with digital multimeters and what types with oscilloscopes?
Question 2: Why is it dangerous to short a voltage source?
Question 3: Use LTSpice to implement and discuss the outcomes of the followings:
a. Modifying the resistors, R1 and R2, to be 10kΩ in the simple AC circuit shown in Fig. 1.2, instead of 1kΩ.
b. Applying a sinusoidal input signal of 20Vpp and 1 kHz in the low pass filter circuit shown in Fig. 1.3, as a substitute of 2Vpp and 10 kHz.
Note: Always do Transient and AC analysis when there are frequency dependent components in the circuit.
c. Modifying the resistor R to be 2kΩ in the High Pass Filter circuit shown in Fig. 1.4, instead of 20 kΩ.
Note: Always do Transient and AC analysis when there are frequency dependent components in the circuit.
Question 4: Determine the nominal value of the resistor, along with its tolerance, equivalent to the following colors of the bands. Use Table 1.1 and eqn. (1.3).
i. Band A, brown; band B, black; band C, red; band D, gold.
ii. A, B, and C bands are yellow and band D is gold.
iii. If the nominal value of the resistor is 10Ω, what would be the best choice of the color bands?
